Developer 777 Coins by 3 Oaks Gaming is a 3-reel, 3-row slot with 5 paylines and a return to player of 95.75%. The base game uses retro-style symbols and Jewel icons, while the layout keeps the format simple for players who prefer a classic reel structure.
The main feature is the HOLD & WIN BONUS. It starts when two Bonus Symbols land with the gold 777 Coin Collect Symbol. The bonus gives three respins, which reset when new symbols appear. During the round, only Bonus Symbols and Collect Symbols can land, with values including Mini, Minor, Major and Grand Jackpot. A Grand Jackpot symbol worth x2,000 can raise the top prize to x6,000 when combined with three Collect Symbols.
The game also includes a metre above the reels that fills as Coin Symbols appear in the main game, triggering the bonus feature when complete. Players can use the demo version to play for free and practice before playing for real money, which allows the bonus mechanics and jackpot structure to be tested without staking funds.
